We've been getting a lot of inquiries about retatrutide pens lately, and HL007 is what we typically push for lab work—it's a 3ml disposable with an adjustable dose from 0.01ml to 0.6ml, which is pretty much the sweet spot for titration studies. It runs on a mechancial push mechanism, so no batteries to die mid-experiment, and you get both a click and a visual cue when the injection is done, usually in under 6 seconds.
31G or 32G needles are standard, and we can go smaller if your protocol demands it. One thing that surprises buyers is the length—17cm overall—which feels a bit more substantial than the stubby pens you see for insulin or GLP-1, but that extra grip helps with consistent thumb pressure. It's not ideal for high-volume subcutaneous dosing over 0.6ml per shot, though; for that you'd want a different setup.
Stock is usually solid on the grey/blue caps, but if you want custom labeling or a different closure, that adds about 2-3 weeks to lead time. We've got the China Class II medical device registration in order, and COAs are available per batch if needed—just flag it on the PO.
And the price? For a class II certified disposable pen with visual and auditory feedback, it's roughly 15-20% below what you'd pay for a comparable European import, especially if you're ordering 500 units or so. That's with the 3ml cartridge pre-loaded in the barrel, by teh way—no separate loading step in your lab.
Actually, most buyers going for retatrutide or other GLP-1 analogue studies go with the 0.01ml minimum adjustment because it gives them finer granularity in. We can also run HPLC on the cartridge fill if you're using your own compound—just confirm that at order time, since it's not standerd.
